I see people still trying to help you on the previous post. Would be good to mark it as solved or just say you are good so no other responses are made…
In step 27 you were asked to swap out the div element for a class element using .menu, which you did correctly on the CSS file, but it looks like you might have also done this in the HTML file - I’m not clued up enough to know why that wouldn’t flag as an error, but because you are now being asked to insert an attribute (generally nested inside an opening tag) into the div element on your HTML file, you can’t physically do that because you don’t have a div opening tag in your HTML file.
